超深水平井完井及采油工艺设计

Design of Well Completion and Oil Recovery Process of Ultra Deep Horizontal Well

完井管柱的优化设计能有效缩短完井周期、提高完井效率,同时对完井后的储层改造方案的实施具有重要的影响。针对超深直井及水平井开展了完井管柱结构的设计工作,实现了完井后可直接实施酸化压裂的完井方案。同时对各类采油工艺展开了探讨,分析了机械采油方式的适应性,制定出更为合理的采油工艺。

The optimal design of completion string can effectively shorten the completion cycle and improve the well completion efficiency, and also has important influence on the implementation of reservoir reconstruction plan after completion. Aiming at the design of well completion string structure for ultra deep horizontal wells, the completion plan for direct acidizing fracturing after completion was realized. At the same time, various kinds o foil recovery technologies were discussed, the adaptability of mechanical oil recovery methods was analyzed, and a more reasonable oil recovery process was worked out.
